The new energy battery air tightness tester is a kind of equipment used to test the sealing performance of the battery. The main principle is to monitor the pressure change inside the battery by injecting a certain pressure of gas into the battery, so as to determine whether the battery has leakage.
In the field of new energy vehicles, the sealing performance of the battery is crucial to the safety and reliability of the product. The following will introduce in detail the operation method of the new energy battery air tightness detector.
First of all, the preparations.
Before using the device, it is important to ensure that the device is in good working order and that the battery under test is ready. First, check if there are normal connections, including the connection of power, air supply, and other circuits. Then, according to the type and specifications of the battery under test, select the appropriate test port and gas port. In addition, it is also necessary to ensure that the temperature, humidity and other factors of the test environment meet the test requirements.
Secondly, the operation steps.
1) Place the battery under test on the test bench and connect with the battery through the device interface. Make sure the connections are well sealed to prevent gas leakage.
2) The test parameters should be set according to the test requirements such as inflation pressure and holding time. Generally speaking, the charging pressure should be higher than the internal pressure of the battery when it is working normally to ensure the test effect.
3) Start for testing. The device automatically inflates the battery before the set pressure value is reached. At this time, a closed gas space is formed inside the battery.
4) Keep the pressure steady for a period of time (usually a few seconds to a few minutes) so that the gas can reach all parts of the battery sufficiently. During this time, the device will monitor changes in pressure in the battery in real time.
5) If the internal pressure of the battery drops significantly within the set time, it indicates that the battery is leaking and the sealing effect is poor; Conversely, if the pressure drop is smaller, it indicates that the battery has a good sealing effect.
6) After the test, the device will be automatically drained and the test result will be displayed on the screen. The operator can judge whether the sealing performance of the battery meets the standard based on the displayed results.
In short, the new energy battery air tightness detector has important application value in the field of new energy vehicles. By mastering the correct operation method, the sealing performance of the battery can be effectively evaluated, and the product quality control can be strongly supported. At the same time, the use of this equipment can help enterprises improve production efficiency, cost and competitiveness.
